Resumo: | With the expansion of the sugar/alcohol sector, the native vegetation was removed from soils with few limitations as well as with great risks for intensive cultivation and the areas incorporated in the production process. Therefore, the adoption of management systems that maintain the soil structure may be a key for the maintenance of the quality and sustainability of sugarcane production systems. The objective of this study was therefore to evaluate the use potential for sugarcane and structural quality of a Dystrophic Haplic Cambisol (CXvbd) (Inceptisol) and Dystrophic Red-Yellow Latosol (LVAd) (Oxisol), in the county of Goianésia, Goiás State. The soils of each area were classified for their use capacity. Disturbed soil samples were collected at depths corresponding to the surface and subsurface diagnostic horizons, for chemical and physical-hydric characterization. Undisturbed samples were collected (from the layers 0–0.05, 0.1–0.15 and 0.3–0.4 m) to determine soil porosity, water retention curves, the least limiting water range and preconsolidation pressure. The evaluation of soils by the land use capacity system indicated that CXvbd belongs to class IVe and LVAd to IIIs. Results of the analysis of the chemical and physical-hydric attributes of the CXvbd indicated that a continuous sugar-cane cultivation, despite the classification as IVe in the use potential system, was due to the adoption of agricultural terraces, aside from the fact that the degrees of soil revolving was lower and of soil cover higher, when sugarcane was harvested green The water availability for plants was highest for CXvbd, which tends to be advantageous for crops. In the study conditions, the LVAd was most susceptible to compaction, which requires limitations of machinery traffic. |

Para isso, a adoção de sistemas de manejo que mantêm a estrutura do solo pode ser a chave para a manutenção da qualidade e sustentabilidade dos agrossistemas canavieiros. Assim, o objetivo deste estudo foi avaliar o potencial de uso para canade-açúcar e a qualidade estrutural de um Cambissolo Háplico Tb distrófico (CXvbd) e um Latossolo Vermelho-Amarelo distrófico (LVAd), no município de Goianésia, GO. Em cada área, realizou-se a classificação das terras quanto à capacidade de uso. Foram coletadas amostras deformadas nas profundidades correspondentes aos horizontes diagnósticos superficiais e subsuperficiais, para caracterização química e físico-hídrica dos solos. Nas profundidades de 0 a 0,05, 0,1 a 0,15 e 0,3 a 0,4 m, foram coletadas amostras indeformadas para determinação da porosidade do solo, da curva de retenção de água, do intervalo hídrico ótimo e da pressão de preconsolidação. O enquadramento dos solos no sistema de capacidade de uso da terra apontou o CXvbd como pertencente à classe IVe, e o LVAd, à classe IIIs. Os resultados das análises dos atributos químicos e físico-hídricos do CXvbd indicaram que o cultivo contínuo com cana-de-açúcar, mesmo com o enquadramento na classe IVe do sistema de capacidade de uso, deve-se à adoção de terraceamento agrícola, além do fato de essa cultura promover pequeno revolvimento do solo e aumentar a cobertura do solo quando colhida crua. O CXvbd apresentou maior disponibilidadede água para as plantas, o que tende a trazer benefícios à cultura. O LVAd, nas condições de estudo, é mais suscetível à compactação, necessitando da adequação do tráfego de máquinas.Sociedade Brasileira de Ciência do Solo2019-10-15T17:49:16Z2019-10-15T17:49:16Z2009info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfSEVERIANO, E. da C. et al.
